1. An ophthalmic information processing apparatus, comprising:
processing circuitry configured as a specifying unit configured to specify a three-dimensional position of each pixel in a two-dimensional front image depicting a predetermined site of a subject's eye, based on OCT data obtained by performing optical coherence tomography on the predetermined site; and
the processing circuitry is further configured as an image deforming unit configured to deform the two-dimensional front image, by changing position of at least one pixel in the two-dimensional front image based on the three-dimensional position, to generate a three-dimensional front image,
wherein
the processing circuitry is further configured as a designation unit used for designating a point of view in a predetermined three-dimensional coordinate system;
the processing circuitry is further configured as a projection unit configured to project the three-dimensional front image onto a two-dimensional plane in the three-dimensional coordinate system in a line of sight direction passing through the point of view designated using the designation unit; and
the processing circuitry is further configured as a display controller configured to display an image on a display unit, the image being projected onto the two-dimensional plane by the projection unit.
